Solar Shingles For Your Roof [Data Facts]
Solar roof shingles are the best possible replacement for traditional solar panels. Although solar shingles have been around for a while, their popularity only spiked when Elon Musk announced his own Tesla solar roof. With a competitive price, sleek design, and unprecedented functionality, solar roof solutions are the best investment for those who do not want to compromise their roof looks and property aesthetics.
What are Solar Roof Shingles?
Solar roof shingles are roof tiles with built-in solar cells. The photovoltaic shingles can, therefore, completely substitute for your roof and look much better than standard solar panels added to the roof. Proponents of the technology also say that roof shingles are more durable than traditional solar panels and that they give multipurpose to the otherwise useless surface: generating electricity and staying protected from the elements now go hand in hand.
As yet another product on the solar market, solar tiles can help usher renewables into daily life and help mitigate climate change. Made from conventional roofing materials, with an added solar cell in each tile, they are a great substitute for building-integrated photovoltaics – a solution many disliked. The newer generation of solar tiles can cover the entire roof and give it a uniform, sleek design that you will want to see, not hide away from.
When choosing solar shingles, there are several factors you should consider. All of these are important in determining what your roof will look like, which brand you will use, how much energy you will get, and lastly, what the cost will be. The factors to consider when choosing solar shingles for your home include:
The lifespan of solar shingles is around 25-30 years. This means that your shingles will generate electricity for the next two to three decades after the installation is done. During this time, your shingles will produce energy that is enough to pay them off, especially as your energy costs will be almost nullified. Conventional shingles cannot do this.
When it comes to the size of your shingles solar array, it can be observed that the size can relate to the size of individual shingles and the size of the total solar array. In the former case, choosing shingles you think will work the best with your existing shingles is the most important factor. In the latter case, the size of your solar system is also important, as it should be large enough to produce all the energy your family needs, especially in the upcoming years. You may need an expert to help you with the calculations.
The number of roof shingles is also important. Here, you need to understand that each shingle produces only a limited amount of energy. This means that you need to divide your total energy needs with the DC output of the shingle model you would like to purchase. As most shingles can produce between 35 and 80 Watts a piece, you will need quite a few to cover your needs.
Bear in mind that the total cost of your installation and the average cost per foot sq. will depend on the ratio between active and inactive shingles. Tesla solar shingles, for example, come with both active and inactive shingles. However, their ratio is determined by your energy needs and roof size.
The material used in your shingles also has a big say in their looks and performance. In general, the basis for the shingles is asphalt, concrete, or metal. The solar cell inside can be polycrystalline or monocrystalline. Alternatively, thin-film solar cells can also be found. Monocrystalline shingles have the highest efficiency, while thin-film technology offers the lowest possible power output.
Different materials mean different efficiency, which, in turn, means differences in the energy generation capacity. With solar shingles, you can generally expect an energy generation capacity of between 35-80 Watts per shingle, which is great considering their cost and the number you need. Always take all these factors into consideration before making your purchase.
How Do Solar Shingles Work?
Solar shingles have been around for a while. They came into the market because many people complained that traditional PV panels simply do not look good enough on their roofs. With the advent of polycrystalline silicon solar cells and thin-film solar panels, the market was finally ready for solar shingles and their production. Thin-film solar cells are inexpensive to produce, but as the technology is still new, the cost of solar shingles is still relatively high.
Solar shingles are installed as regular shingles: they are mostly either screwed or nailed in place. Once there, they are connected either in series or using parallel connections and connected to your solar inverter and the solar battery. Once everything is connected, they act as regular solar panels, producing electricity when exposed to direct sunlight.
One of the biggest solar shingles pros is that they produce solar energy and act as a traditional roofing material. You get to use renewable energy in your home and do so at a high conversion efficiency: some solar shingles use monocrystalline technology – enabling around 20% conversion efficiency.
Types of Solar Roofing
As solar shingles became more popular over time, other types of solar products started appearing. Solar shingles or solar roofs became so popular because they already included the cost of replacing the roof and reduced the need to look for two separate contractors: one to replace the roof and one to install PV panels. For this reason, two new products have sprung up in the solar market:
Integrated Solar Metal Roofing
Integrated solar metal roofing is a type of multi-layer metal roofing that consists of glass coating, color, and a monocrystalline layer. The wiring and all other electrical components are hidden under metal for a clean look. The entire system is placed on a vented racking system, increasing its efficiency and power output.

Interlocking Solar Panel Roofing
In response to the ever-increasing of solar roofs, GAF and Suntegra introduced interlocking solar panel roofing. This kind of roofing helps you avoid the solar shingle cost and all the additional work accompanying solar shingles. A system like this is easy to install, competitive in price, and it makes a good compromise in an aesthetic sense, especially between regularly mounted solar panels and an interlocking, integrated system.
Tesla has installed very few solar roofs, despite Elon Musk’s hype
The Tesla CEO claimed a few years ago that the company would be installing 1. 000 solar roofs a week — but last year it averaged just 21 a week, a new report finds.
In 2019. Tesla CEO Elon Musk boasted, “ This is the year of the solar roof.” The next year, he said the pioneering EV company would soon be installing 1. 000 integrated solar roofs tailored to the building per week.
It turns out that 2019 absolutely was not the year of the solar roof — not even close. And neither was 2020. nor any year since. This reporter estimated in 2021 that Tesla had installed fewer than 1. 000 integrated solar roofs total — an assessment bolstered by new analysis.
A report released today by energy consultancy Wood Mackenzie estimates that Tesla has installed approximately 3. 000 solar roofs in the U.S. since the launch of the product in 2016. That’s several hundred thousand roofs short of Musk’s hallucinatory forecasts.
WoodMac analysis finds that average installations per week were a scant 21 in 2022. The best quarter for Tesla solar roof installations was the first quarter of 2022. which saw an average of 32 systems deployed per week — still a far cry from 1. 000.
Get Caught Up
Other companies have a lead in building-integrated solar
Tesla’s solar roof product is what’s referred to as building-integrated photovoltaics ( BIPV ), which are solar-generation surfaces that are not mounted on a structure, but rather form the actual roof, Windows or building envelope. There are a number of experienced building-integrated photovoltaic designers and installers operating today, such as GAF Energy, CertainTeed, ArteZanos and Forward, but so far, BIPV remains a niche market for custom roof designs on expensive buildings in regions with generous solar subsidies. There is a long list of failed BIPV efforts.
Reaching the end customer with an integrated solar roof is not a technical or financial problem — it’s a channel problem. You’re looking to drive a completely new type of product through the very conservative roofing channel, and that’s a daunting marketing challenge. Traditional solar modules on racks may be less than aesthetically perfect, but rooftop solar installers have a distribution channel along with technical expertise.
That’s why GAF Energy, which had already installed several thousand integrated solar roofs as of a year ago, might have an advantage over Tesla. GAF Energy is a Standard Industries company and sister company to GAF. one of the world’s largest roofing companies. GAF Energy President Martin DeBono told Canary last year that GAF developed the product by thinking like a roofing company, not a solar company. He said the roofing industry is 20 times larger than the rooftop solar industry and has a huge advantage in scale.
We would have reached out to Tesla’s public-relations team for comment on WoodMac’s report — but Tesla does not have a public-relations team.
UPDATE : Tesla disputed the WoodMac study’s findings in a tweet, but offered no specifics.
How Does the Tesla Solar Roof Work?
The first few attempts at BIPV solar roofs were made by pasting flexible solar panels over regular shingles. However, it was an inefficient method with questionable durability.
When Tesla got into the solar game and designed its solar roof tiles with subsidiary SolarCity. it integrated solar cells directly into the shingles (initially using a Panasonic cell before parting ways with the company). 1 This makes the solar cells almost impossible to spot.
A Tesla Solar Roof comprises two types of roof tiles — active and inactive. They look identical, but the active tiles generate power and the inactive do not. Most homes only need part of their roof to be covered in active tiles to offset their energy bills. The inactive tiles can be strategically placed in shady spots to maximize the efficiency of the active tiles while maintaining a seamless design.
Solar shingles generate direct current (DC) power, so a Tesla roof also needs an inverter to turn it into usable alternating current (AC) power for your home. Tesla recommends adding a Powerwall battery to the system as well. This lets homeowners store solar energy for use at night or as backup power during a grid outage.

How Much Does the Tesla Solar Roof Cost?
We evaluated a typical house in California with a 2,000-sqare-foot roof and an average electric bill of 150 per month. According to Tesla, such a home would require a 6.14 kilowatt (kW) Solar Roof. Along with the recommended Powerwall, this would cost 48,300 after factoring in incentives like the federal tax credit (the system would cost 69,000 without the tax credit).
Without an energy storage system, the roof would cost about 45,200. Tesla also charges for tearing off an existing roof. In this example, roof removal costs 7,700.
Here’s a breakdown of Tesla roof pricing for the home we analyzed:
Tesla describes these costs as “estimated costs” and has a disclaimer stating that the may change based on actual installation and roof removal conditions.
This change was reportedly made after some homeowners were asked to pay more after signing a contract for a certain purchase cost. If you decide to go ahead with the quoted prices, you will be required to pay a 250 refundable deposit.
What Affects the Cost of a Tesla Solar Roof?
Below are the main variables that cause the total installation cost of your Tesla Solar Roof to be higher or lower
- Roof complexity
- Size of your roof
- Necessary home upgrades
- Cost of labor
According to Electrek 2. Tesla introduced its own roof complexity factor that impacts the price of its solar shingles and solar roofs. Your roof’s complexity is taken into account within the online quote system which makes it much easier to give you an accurate estimate for your solar panel installation. On Tesla’s online quote page, you’ll be asked about the following to determine your roof’s complexity:
- Number of roof joints
- Pitch of your roof
- Presence of chimneys, ventilation, dormers and other features on your roof
Tesla’s pricing system does not yet have the capability to rate the complexity of your roof, but it is not unheard of to see an added cost of 5,000 to 10,000 depending on how your roof rates. To gauge how complex your roof is according to Tesla’s standards, you can use this general system:
- Simple : Your roof has only one level, a low pitch and very few extra features
- Intermediate : Your roof has at least two levels, a moderate pitch and more than two extra features, such as a dormer window and chimney
- Complex : Your roof has several levels, has a steep slope and has several extra features
Size of Your Roof
The larger your roof, the more expensive your Tesla Solar Roof will be. Not only do larger roofs require more material, but larger roofs take longer to install simply because of the added square footage. Not every homeowner will know the size of their roof down to the square foot, so online estimates may differ from in-person quotes.

Necessary Home Upgrades
When you complete Tesla’s online quote system, you will be given a general estimate for the cost of your new solar roof. However, this quote does not include any extra home upgrades or add-ons that may be necessary to complete your project.
Before the installation process can begin, your solar technicians may need to update existing electrical wiring or remove old roofing. If your solar roof needs to be installed on your shed or deck, this can also increase the price. You may not be able to get this added cost information online, but it will be included in your roof inspection.
Cost of Labor
Cost of labor has a major impact on the cost of your Tesla Solar Roof, and this price can vary depending on where you live. For instance, the cost of labor may be different if you live in New York versus if you live in Texas. This cost can even vary from town to town and from one contractor to the next.
Tesla Solar Roofs are not a simple task for a roofer either. If your roofer doesn’t have experience with Solar Roofs, labor costs can add up quickly due to the extra time needed to plan and execute the complex installation.
Tesla Solar Roof vs Other Solar Options
The price of solar shingles is typically more expensive upfront and costs between 25,000 and 60,000 for a 1,700-square-foot roof. However, many homeowners ultimately choose solar shingles over traditional solar panels due to their modern appearance and low maintenance. See how the Tesla Solar Roof compares to other leading solar shingle providers in the industry.
What other roof can help pay for itself over time?
With Solar Roof, you can add value to your home and lower your electric bill with solar PV tiles integrated right into your shingles.
Plus, Tesla Solar Roof can even increase your roof’s solar capacity when compared to traditional solar panels.
